HEAT INDEX – are human discomfort index that gives the "apparent" temperature or what human perceive or feel as the temperature affecting their body. High air temperatures and high relative humidity will give high apparent temperatures or indices. Full exposure to sunshine can increase the heat index by 8°C.

  1. Stay indoors as much as possible, if air conditioning is not available, stay on the lowest floor out of the sunshine.
  2. Wear lightweight and light colored clothing. Light colors will reflect the sun's energy.
